"For all their deficiencies, the Hitler Youth movement and the increasingly Nazified school system were driving a wedge between parents who still retained some loyalty to the beliefs and standards they had grown up in themselves, and their children who were being indoctrinated at every stage of their lives. As one such agent ruefully observed: ‘It is extremely difficult for parents who are opponents of the Nazis to exercise an influence on their children. Either they ask the child not to talk at school about what is said at home. Then the children get the feeling, aha, the parents have to hide what they think. The teacher permits himself to say everything out loud. So he’s bound to be right. - Or the parents express their opinion without giving the child a warning. Then it’s not long before they are arrested or at the very least called up before the teacher, who shouts at them and threatens to report them. - ‘Send your father to the school!’ That is the normal answer to suspicious doubts and questions on the part of the child. If the father is quiet after such a visit, then he gives the child the impression that he has been convinced by what the teacher has told him, and the effect is far worse than if nothing had ever been said.’"
